Question

我几乎没有关于javascript的任何想法。我看了一些视频，为我的项目进行实时聊天，我收到了这些错误。

注意：在此实时聊天工作之前，只是简单的事情发生了，现在它不起作用，我真的不知道为什么会发生这种情况。我需要你的帮助，提前谢谢你！..

app.js:59006 Uncaught ReferenceError: Echo is not defined

当我按此错误时显示：

Echo.join('chat').here(function (users) { X

    __WEBPACK_IMPORTED_MODULE_0__bus__["a" /* default */].$emit('users.here', users);
}).joining(function (user) {

    __WEBPACK_IMPORTED_MODULE_0__bus__["a" /* default */].$emit('users.joined', user);
}).leaving(function (user) {

    __WEBPACK_IMPORTED_MODULE_0__bus__["a" /* default */].$emit('users.left', user);
}).listen('MessageCreated', function (e) {

    __WEBPACK_IMPORTED_MODULE_0__bus__["a" /* default */].$emit('messages.added', e.message());
});

bootstrap.js

require('./echo')

import Echo from "laravel-echo"

window.Pusher = require('pusher-js');

window.Echo = new Echo({
    broadcaster: 'pusher',
    key: Laravel.keys.pusher,
    cluster : 'eu',
    encrypted : true
});

查看部分

   <script src="{{ asset('js/app.js') }}"></script>

    <script>

        window.Laravel = {!! json_encode([

            'csrfToken' => csrf_token(),
            'user' => [
                'authenticated' => auth()->check(),
                'id' => auth()->check() ? auth()->user()->id : null,
                'name' => auth()->check() ? auth()->user()->name : null
            ],

            'keys' => [
                'pusher' => config('broadcasting.connections.pusher.key')
            ]

        ]) !!};
